Afghanistan's Northern Alliance leaders and representatives of exiled Afghan King Mohammad Zahir Shah are reported to have agreed on a formula for establishing an interim post-Taleban parliament to govern their war-torn country.

Few details of the deal have emerged from the talks in Bonn. But foreign diplomats observing the negotiations say all four Afghan delegations have agreed on the makeup of what they are calling an interim council.

A United Nations' observer said delegates were still trying to work out details today (Thursday).

The Bonn conference is aimed at forging a consensus among Afghan factions to form a broad-based, multi-ethnic government. The Northern Alliance, representatives of the former king and two other groups of exiled Afghans are attending the conference, which is expected to last several days.

Earlier, the head of the alliance delegation, Younus Qanooni, said his group would support a role for the exiled king in a future government if it is recommended by a grand assembly of tribal chiefs at a meeting set for next year.

Mr. Qanooni also said the alliance would accept an international peacekeeping force -- if it is part of a comprehensive peace package.
